如果出现了 No value specified for parameter 15， 那一定是15（从0号开始）号位的参数缺失。

mybatis打印出的SQL的问号有30个，而下面的参数只有29个。确实是没对应上。

一次写两条记录，一条有值一条没值，再排查对应字段的typehandler

	@Override
	public void setNonNullParameter(PreparedStatement ps, int i, List<AgreementParam> parameter, JdbcType jdbcType) throws SQLException 
		if (CollectionUtils.isEmpty(parameter)) 
			return;
		
		
		ps.setString(i, JSON.toJSONString(parameter));
	

如果参数为空，直接return了。没有给PreparedStatement对应参数位设置值，即便是null也没有。所以问题在这里。
